Microscopic crystals extracted from meteorites could help settle a debate about the birth of our patch of the Milky Way.
About 4.6 billion years ago, the Solar System formed from a cloud of dust and gas collapsing in on itself due to gravity. The Sun, planets, and eventually Earth formed out of the cloud. But when did ...
A small, round piece of asteroid Ryugu (sample #91), called “S-lunar,” contains tiny particles (less than 1 mm) that will allow planetary scientists to study the magnetic signature of the early solar ...

A new paper in Monthly Notices of the Royal Astronomical Society argues the simplest answer may work: contact binaries like Arrokoth can form directly during the gravitational collapse of a dense ...
The workings of our solar system are roughly the same now as they have been for millions of years. Moons circle their planets, the planets circle the sun, the sun’s magnetic fields and sunspots wax ...

'Mass migration' of stars from the Milky Way's center could explain why there's life in our solar system
The Gaia telescope spotted more than 6,000 sunlike stars, all of which appear to have migrated from the galaxy's center more than 4 billion years ago.
